STRUCT SLF3S_DATA(9)

💖 struct slf3s_data — per-device state 💖

okay so bestie, welcome to the struct slf3s_data page from the Kernel API Manual ✨ this is the little per-device state bundle that keeps track of, like, everything one SLF3S chip needs to remember about itself. it's giving "main character energy" but for a single I2C device 🫶

✨ SYNOPSIS ✨

struct slf3s_data {
    struct i2c_client *client;
    struct regulator *vdd;
    const struct slf3s_variant *variant;
    enum slf3s_medium medium;
    struct mutex lock;
    u8 crc_table[CRC8_TABLE_SIZE];
 };

no cap, that's the whole struct 💅 copy it exactly, don't go "fixing" the indentation, the compiler does not care about your aesthetic ✨

🎀 Members 🎀

• client — the I2C client this instance is bound to 🔥 like, the actual connection this whole vibe is attached to.
• vdd — the supply regulator, and it's disabled while suspended 😴 so yeah, it goes to sleep when the system does.
• variant — a pointer into slf3s_variants for the detected device 👑 iykyk, it's the "which chip are we even talking to" pointer.
• medium — the currently active calibration medium 🧪 literally the current calibration vibe.
• lock — a mutex that serialises the multi-step command/response exchanges 🔒 because those exchanges are a whole conversation and you canNOT have two people talking at once, periodt.
• crc_table — the pre-computed CRC-8 lookup table for SLF3S_CRC8_POLY 🌈 already calculated, already iconic, no runtime math needed.

and that's the whole page, bestie 🎀 this one came from ./drivers/iio/flow and it's dated October 2026 — slay, go forth and reference structs responsibly 💅✨🌸
